+## How Does It Work? 🌟
+
+**MicroStream** simplifies communication between microservices using a **centralized hub-and-spoke architecture**, also known as a **star network**. In this model, the **[MicroStream Hub](https://github.com/arijitcodes/microstream-hub)** acts as the central communication point, and your microservices, equipped with the **[MicroStream Client](https://github.com/arijitcodes/microstream-client)**, connect to the Hub and communicate through it.
+
+Here's how it works:
+
+### 🌟 The Star Network Concept
+
+Imagine a star:
+
+- The **center of the star** is the **[MicroStream Hub](https://github.com/arijitcodes/microstream-hub)**.
+- The **points of the star** are your **microservices** (each equipped with the **[MicroStream Client](https://github.com/arijitcodes/microstream-client)**).

+
+In this setup:
+
+- The **Hub** acts as the central communication point.
+- **Services** (nodes) connect to the Hub and communicate through it, **not directly with each other**.
+
+### 🚀 How It Works in Practice
+
+1. **Service Registration**:
+
+   - Each microservice connects to the Hub using the **[MicroStream Client](https://github.com/arijitcodes/microstream-client)**.
+   - The **[Hub](https://github.com/arijitcodes/microstream-hub)** automatically detects and registers the service.
+
+2. **Request-Response Communication in Real-Time**:
+
+   - When **Service A** needs to talk to **Service B**, it sends a request to the **[Hub](https://github.com/arijitcodes/microstream-hub)**.
+   - The **[Hub](https://github.com/arijitcodes/microstream-hub)** routes the request to **Service B**.
+   - **Service B** processes the request and sends a response back through the **[Hub](https://github.com/arijitcodes/microstream-hub)**.
+   - All communication happens in **real-time** over WebSockets, ensuring fast and reliable data exchange.
+
+3. **Auto-Discovery**:
+
+   - Once connected, the **[Hub](https://github.com/arijitcodes/microstream-hub)** keeps track of all connected services, so you don’t need to manually configure connections between services. However, you still need to specify the target service and method when sending a request.
+
+4. **Heartbeat Mechanism**:
+   - Services send regular "heartbeats" to the **[Hub](https://github.com/arijitcodes/microstream-hub)** to confirm they’re active.
+   - If a service stops sending heartbeats, the **[Hub](https://github.com/arijitcodes/microstream-hub)** removes it from the network.
+
+### ✨ Why Choose MicroStream?
+
+**MicroStream** is designed to make microservice communication **simple**, **efficient**, and **scalable**. Here’s why you’ll love it:
+
+- **Easy Setup**: Minimal configuration required to get started.
+- **Real-Time Request-Response Communication**: Built on WebSockets for instant, reliable data exchange.
+- **Auto-Service-Management**: Once connected, the **[Hub](https://github.com/arijitcodes/microstream-hub)** keeps track of all services, simplifying network management.
+- **Scalable**: Easily add more services without reconfiguring the network.
+- **Lightweight**: Minimal overhead compared to traditional REST or gRPC.
+- **Flexible**: Works seamlessly with any microservice architecture.

 2. **Registering Handlers**: The `onRequest` method is used to register a handler for incoming requests. In this example, the handler responds to an "authenticate" event.
    - **Parameters**:
      - `event`: The event name to listen for.
